【Abstract】 In this paper, the FE numerical simulation of the thermal-rheological forming of aluminum alloy (Lc4)part (shown in Fig.1) was carried out, including the numerical simulation of rheological process in the mold cave, velocity field, equivalent stress field, equivalent strain field, equivalent temperature field etc.,the results of which not only were similar to the actual situation, but also testified the results derived theoretically form literatures.更多还原
